Add Freight cost to purchase invoice without adding to item costs

I’ve read the guide relating to Freight-in and understand how that works but It’s doesn’t suit my needs. Manually adding freight to each item would be very time consuming and letting it be added automatically by item cost works in reverse to what I need as I have a lot of heavy low cost but high profit items.

I’d rather add the freight cost into the purchase invoice to balance it but treat that cost as an expense, not perfect but I think it will work for me.

I’ve set up a Freight incoming goods account in the chart of accounts as an expense, then created an inventory item of Freight incoming goods, ticked the custom expense account and selected Freight incoming goods account.

I hope I’ve explained that clearly, is this best way for what I’m trying to achieve ?

Do not create Freight incoming goods as an inventory item.

Just select Freight incoming goods expense account and leave the Item column empty.

If you really insist for item to be selected, then create Non-inventory item and have it linked to expense account of your choice - e.g. Freight incoming goods

Thank you for fast response and giving me the correct solution.
